Merge tag 'iommu-updates-v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu

Pull iommu updates from Joerg Roedel:

 - Intel VT-d driver updates:
     - Domain force snooping improvement.
     - Cleanups, no intentional functional changes.

 - ARM SMMU driver updates:
     - Add new Qualcomm device-tree compatible strings
     - Add new Nvidia device-tree compatible string for Tegra234
     - Fix UAF in SMMUv3 shared virtual addressing code
     - Force identity-mapped domains for users of ye olde SMMU legacy
       binding
     - Minor cleanups

 - Fix a BUG_ON in the vfio_iommu_group_notifier:
     - Groundwork for upcoming iommufd framework
     - Introduction of DMA ownership so that an entire IOMMU group is
       either controlled by the kernel or by user-space

 - MT8195 and MT8186 support in the Mediatek IOMMU driver

 - Make forcing of cache-coherent DMA more coherent between IOMMU
   drivers

 - Fixes for thunderbolt device DMA protection

 - Various smaller fixes and cleanups
